Audio Precision 2722

產品描述

The Audio Precision 2722 Audio Analyzer is the flagship model of Audio Precision’s award-winning PC-controlled audio analyzers, long the recognized worldwide standard for the design and test of audio equipment. The fullfeatured SYS-2722 provides the unmatched distortion and noise performance required to test the latest advances in converter technology, combined with 192k digital input and output capabilities. The AP SYS-2722 features true dual domain architecture which enables uncompromised measurement of both analog and digital signals: the hardware generator and analyzer specifications surpass those of any digital configuration, while digital analysis techniques offer a wide array of precise, high-speed measurement techniques for either domain. Cross-domain work can be accomplished using the best of both worlds. Features of the Audio Precision SYS-2722 Audio Analyzer include: The unparalleled precision of a dedicated hardware instrument. Fast instrument operation and powerful analysis under sophisticated control software. Programmatic control for high-speed automation. Serial digital interface testing. Flexible configuration options. A family of auxiliary instruments for specialized testing. AES3, IEC60958 (SPDIF) and PSIA input and output sample rates at 192 kHz. Specifications of the System 2 SYS-2722 Cascade include: Low Distortion Analog system 1 kHz THD+N, 20 kHz BW = –112 dB (Typical worst case harmonic < –130 dB) Digital generator distortion/spurious products =– 160 dB High Bandwidth Analog signal generation to 204 kHz Analog measurements to 500 kHz Analysis by FFTs and Multitone to 120 kHz Low Noise Analog analyzer 22 Hz–22 kHz BW = –118 dBu Analog analyzer A-weighted = –124 dBu Flat Response Analog system 20 Hz–20 kHz Typically ± 0.003 dB Low Crosstalk Analog inputs 20 Hz–20 kHz = –140 dB Analog output 20 Hz–20 kHz = –120 dB Low Jitter 700 Hz–100 kHz BW = 600 ps 50 Hz–100 kHz BW = 1.0 ns FFT Acquisitions Up to 4 M Samples (87 s @ 48 kHz Fs)
